Invoice cancelled and distribution lines incorrect

HI all,

I have looked for a similar  issue but have been unable to fine a fix/help. We are currently running 11.5.2.

I have a cancelled invoice that has an outstanding balance in a tax account, the accounting reversal did not debit withholding tax in the distributions when cancelling the invoice took place.

The accounting has been created and the invoice distribution is 0.00. However when i look into accounting and T- accounts there is still a  credit of 8.00 in the withholding tax account.

Is there a script to un-cancel the invoice and manually reverse the tax? Also could someone explain why the withholding tax reversal line did not take place.
